FilterMode.Trilinear

설명

Trilinear filtering - texture samples are averaged and also blended between mipmap levels.

For textures without mipmaps, this setting is the same as Bilinear.

See Also: Texture.filterMode, texture assets.

//This script changes the filter mode of your Texture you attach when you press the space key in Play Mode. It switches between Point, Bilinear and Trilinear filter modes.
//Attach this script to a GameObject
//Click on the GameObject and attach a Texture to the My Texture field in the Inspector.
//Apply the Texture to GameObjects (click and drag the Texture onto a GameObject in Editor mode) in your Scene to see it change modes in-game.
